PATENT HAY-PRESS.

SPECIFICATION forming part of Letters Patent N o. 728,066, dated May -1 2,y 1903.

Application iiledrAugust 18, 1902. Serial No. 12,I14. (o modell) T0 all whom, t may concern,.-

Be it known that I, JOHN THOMAS WEIGHT, of Columbia, in the county of Mau ry and State of Tennessee, have invented certain newand useful Improvements in Hay-Presses; and I hereby declare that the following is a full, clear, and exact description thereof,reference being had to the accompanying drawings, which form part of this specification.y

Thisinvention is an improvement in presses for balng hay, &c., of the type known as rebounding plunger presses, in which the plungers are actuated by a sweep, usually drawn by horse-power, the construction being such that two or more reciprocations are imparted to the plunger for each rotation .of the sweep.

The present invention consists in the several improvements in the construction of suchV presses hereinafter claimed, and the accom'- panying drawings illustrate a press embodying the invention and which will be fully nnderstood from the following detailed description thereof.

Figure'l represents a perspective view of the complete press. Fig. 2is an'enlarged detail vertical longitudinal section through the plunger and operating devices. Fig. 3 is a detail plan view of the apparatus. Fig. 4 is a transverse section on line 4 4, Fig. 3, and Fig. 5 is a section on lines 5 5, Fig.

A designates the baling-box, Which may be of any desirable construction, and B the plunger `working therein. This plunger is connected to a sliding beam or piston-rod b, which is guided in metal loops C, securely bolted to an extension a of 'the base of the box A. The outer end ofthe piston-rod b is pivotally connected to the inner end of the pitman D, which in turn is journaled to the crank e of a crank-shaft E, which is vertically journaled in bearings attached to the upper and lower bars fand f of a power-frame f3, the side bars f2 of which are rigidly connected to the bars f and extend inwardly toward the box A. The bars' f2 converge, and their inner extremities are rigidly connected by boltsto the outer end of the extension a o f the base.

In practice I propose to make'the extensions ct of one or two beams and have the piston-rod b work closely thereto, so that it will not be difcult for the draft-animals to step 'which is a triangular frame formed of two side bars h and top and-bottom plates h', which are preferably formed of metal and bolted to- "2.1

gether and clamped to the ends of bars h, as indicated in the drawings. Between plates h is a ratchet-wheel E, rigidly fixed to the crank-shaft and adapted to be engaged by eithervor both of the opposite pawls H', pivotally secured between the base-plates h' of the sweep, said pawls being normally held in mesh with the ratchet E by suitably-arranged springs H2. The crank-shaft projects-above the sweep, and its upper end is tapered, as shown, and terminatesin a reduced threaded portion e2. On the conical upper end of the shaft E is swiveled a loose ring h3, which is conned thereon by a nut e3, and the ring h5 is connected by a :rod h4 to the outer end of the sweep H and serves to support the latter, as is evident.

The box A and-the power-frame F may be connected by means of tie-rods I, the outer ends of which areattached to bar f, and their inner ends are attached 'to the box A, as shown. These tie-rods are bent in toward and conined to theloops Cby means of clips c, attached to said loops, or in other suitable manner, sothat the tie-rods will not interfere or obstruct the draft-animals in stepping over Athe' plunger-rod b and part a of the frame. The plates fand f are provided with metal bushings f4 and f5, in whichv the crankshaft E is journaled. The power-frame F may be further strengthened by means of the crossed brace-rods'f, attached toits bottom, as shown. The brace-rods I tie the box A and power-f rame together and keep them from spreading apart under the great strains to which they are subjected, and these tie-rods LII also serve as guards above the working plunger and beams b and prevent the animals from stepping thereon.

In operation as the sweep is rotated the pawls engaging the ratchet E rotates the crank-shaft therewith, and this through the pitman forces the plungerinward; but when the crank moves past the inner dead-center of its movement the spring comes into action and retracts the plunger rapidly, throwing the crank-shaft around to the position indicated in Fig. l, where it may stop momentarily until the pawls again catch the ratchet and operate the plunger. Thus for each r0- tation of the sweep two reciprocations of the plunger are eected. As the plunger-beam b has nolateral movement, injury to the draftanimals stepping thereover is avoided, and as the extension a of the frame and the beam b are comparatively narrow the animals can readily step thereover.

What- I desire in my invention to protect by Letters Patent is- 1. In a hay-press, the combination of the hay-box, theplunger therein, the powerframe, the crank-shaft journaled therein, a pitman pivotall y connected to the crank-shaft and plunger, and a spring for causing the rebound of the plunger, the rigid base-bar connection between the plungerand power-frame the tie-rods attached to the upper end of power-frame, converging inwardly and downwardly over the base-bar, and connected to the inner end of hay-box, and the clips for holding said rods to the 'base-bar; with the sweep pivoted on the upper end of the crankshaft, the brace-rod connecting the upper end of shaft and sweep, a ratchet on the shaft and pawls on the sweep adapted to engage the ratchet, all substantially as described.

2. The herein described hay-press, comprising the hay-box, the power-frame, the base-bar connecting the box and frame, the plunger in the box, guide-loops for the plunger attached to said basebar, a crank-shaft journaled in power-frame a pitman pivotally connecting the crank-shaft and plunger, a spring for retracting the plunger; tie-rods connected V to the upper partoi the power-frame, and converging toward and secured to the inner end of the hay-box, the clips attached to the loops and confining the tie-rods, a sweep loosely pivoted on the upper end of the crank-shaft, the sweep brace-rod pi voted on the upper end of shaft and connected to the sweep, and pawl-and-ratchet devices whereby the sweep causes the crankshaft to rotate, all substantially as and for the purpose described.

In testimony that I claim the foregoing as my own I affix my signature in presence of two witnesses.
